SGREEN FOR PIVOTED WINDOW SASHES.

Application filed Apri1 29, 1920. Serial No. 377,577;

To aZZw/lom it may concem. i

, Be it known that I, ALFRED M. LANE, a citizen of the United States,and a resident of the city of St. Louis and State of Missouri, haveinvented a new and useful Improveinent in Screens for Pivoted W'indowSashes, of which the following is a specification. This inventionrelates principally to pivoted window sashes or ventilators, and moreparticularly to the application of window screens thereto. The commonmethod of screening windows with pivoted sashhas been to cover thewindow opening with a basket screen, that is, a screen of semicircularform to accommodate the outwardly swinging lower half of the sash. Theap plication of the basket screen is usually made from the outside ofthe building and necessitates the building of a scaffold to support theworkmen and, therefore, is quite expensive. This form of screen alsogives the building an unsightly appearance from the outside. Theprincipal practical disadvantage of the above type of screen is thedifficulty of making a tightjoint between the adjacent meeting edges ofthe window screen and the swinging sash.

One of the principal objects ofthe present invention is to providescreens for windows of the swinging sash type which can be easily andcheaply applied and which will accommodate themselves to the swingingmovement of the window sash and at the same time maintain a tight jointbetween the meeting edges of the sash and screen. Another object is todispense with the use of separate fastening members for securing thescreens in position and thereby minimize the time and expense ofmounting and dismounting the screens. The invention con- 'sistsprincipallyin the improved manner'of attaching the window screens towindows having pivoted sashes or ventilators, and it also consists inthe combinations and arrangements of parts hereinafter described. In theaccompanying drawings, which form part of this specification, whereinlike synibols refer tolike parts wherever they occur, Fig. 1 is aninterior side 'view of portion of a steel window frame having ahorizontally pivoted sash or ventilator, a window screenmounting'embodying the present invention being shown in connectiontherewith;

- Fig. 2 is a vertical section through the window, thesection beingtaken through the 'middle portion of the window and screens 'on the line2-2 in Fig. 1, the sash'being shown partly open;

Fig. 8 is a notched vertical section taken through the middle portion ofthe sash, showing the hinged connection between the lower portion of thescreen and the middle portion of the sash, the section being taken onthe line 3-3 in Fig. 1; V

Fig. 4 is a horizontal section taken through the upper portion of thewindow frame, showing the manner of attaching the guide and retainingmember for the upperscreen; Fig. 5 is a vertical section through theupper portion of the lower screen and the adjacent middle portion of thesash, showing the hinged connection between the upper edge of the lowerscreen and the sash; and

Fig. 6 is a View similar to Fig. 5 showing a modified means for closingthe joint between the upper edge of the lower screen and the sash.

In the drawings, the invention is shown in connection with a steelventilator window unit 10 having a horizontally pivoted steel sash ll.of the type used for lighting and ventilating factories, oflicebuildings andv the like; but the invention is applicable to other typesof swinging windows having wooden frames and sashes.

The window frame 11 shown in the drawings comprises spaced horizontallyand vertically disposed steel, bars or 'mullions 12, forming rectangularopen spaces in which are fitted glass panes 13. The mullions are of Tshaped section, forming rabbets in which the panes of glassare set. Theside margins of the panes of glass are set in these rabhets behind thehead portions of the mullions with their edges located adjacent to thestem portions of the mullions and are held in this position, as by meansof putty or clips. At their points of intersection, the bars or mullionsare welded or otherwise secured together. A rectangular open space ofthe desired size is left in the frame and in this opening is mounted thesash 11. The middle portion of this sash is attached to the verticalbars of'each side of the sash opening to swing in a vertical plane bymeans of butt hinges l i, which. are secured to the adj acent parts ofthe vertical frame'and sash bars. One of the leaves of a hinge issecured to the frame bar and the other leaf is secured to the adjacentsash bar, the two leaves being held together by means of a horizon talpin or pintle.

The frame of the sash is made up of metal bars comprising top, bottomand side rails 15, and the sash is divided into rectangular open spacesby horizontally and vertically extending mullions 16 of. a shape asimilar to the mullions 12 of the frame 10.

Glass panes 17 are set in these spaces and are held therein in a mannersimilar to those of the frame openings. The top, bottom and side rails15 of the sash are provided with flanges 18 which cover the jointsbetween the top, bottom and side edges of the sash and the adjacent barsof the frame and also act as stops to prevent the sash from swingingbeyond its vertical position when closed. The flanges of the top andside rails on the upper half of the sashare located on the inner face ofthe sash, the side flanges terminating at a point above the hinges 14,and the flanges of the bottom of the side rails of the lower half of thesash are located on the outer face of the sash, the side flanges of thelower half terminating at a point below the hinges 14m Thetop, bottomand side rails of the frame are provided with inwardly projectingflanges 19 which are disposed on opposite sides of the frame above andbelow the hinges, and act as stops for the sash and also close thejoints between the sash and frame in a. manner similar to the flanges 18of the sash.

The up er screen 20 shown in the accoml l 1 panying drawing has a metalframe of tee hind shown and described in my Patent No.

' 1,350,027, dated August 17, 1920, and comprises frame members 21. and22 and a meshwork 28 locked therebetween. The upper screen is placedacross the upper half of the sash opening on the exterior side of theframe. The upper screen has a hinge or mounting member 24 clampedbetween the lower frame members 21 and 22 thereof. The hinge member 24projects downwardly from the lower frame member of the screen and has aloop or beaded portion 25 at its lower margin. This loop portion isadapted to cooperate with the groove or socket portion 26 of a similarmounting member which is secured to the middle horizontal mullion of thesash by means of screws 28. The groove or socket portion of the mountingmember 27 is not entirely closed, thus leaving an open throat portionthrough which the loop or beaded portion 25 of the mounting member 24may be inserted. The hinge members 241- and 27 extend the full width ofthe screen, which is of slightly less width than the sash opening andits vertical dimension is of such length as to permit the upper edgethereof to extend beyond the upper end of the frame. When the lowerportion of the sash is swung outwardly, the

screen 20, by reason of its offset hinge connection with the sash, islifted upwardly and its bottomrportion is thrown outwardly a slightdistance.

The upper end of the upper screen is held against the top rail of thestationary frame and the space betw en the side margins of the screenand the side rails of the frame is closed when the sash is open by meansf plates 30. These members also act as therefrom. The plates areprovided with re aining strips 32 of angular section, one

is riveted or otherwise secure-o. to the outer margins of the guideplates. The other flange projects inwardly and laps the adjacent sidemargins of the screen. if desired, the outer marginal portion of theplates 30 may be flanged inwardlv totake the place of the angle stripsThe guide strips 30 are made wider at the bottom than at the top,thereby leaving a greater space between the lower ends of the anglestrips and the frame at the bottom thereof than at the top toaccommodate the outward movement of the lower portion of the screen whenthe sash is open. Thus, when the sash is swung open, the upper screenwill move upwardly between the guide plates and accommodate itself tothe movement of the sash. The flanges of the guide and retaining stripsare set at an angle which corresponds to the angle assumed by the screenwhen it is in its extreme open position.

The lower half of the sash opening is covered with a screen 35. Thisscreen is of similar construction to the upper screen 20 and is attachedto the bottom rail of the sash by means of clips 36. The screen is of awidth sufficient to enable the side margins thereof to extend beyond theside rails ofthe sash frame, and its upper edge terminates a shortdistance below the sash pivots. A hinge member 37 is clamped be tweenthe top frame sections of the screen and has a curled upper marginalportion in the form of a bead 38. As shown in Fig. 5, the bead portion38 of the hinge member 87 cooperates with a groove or socket portion 39of a similar hinge member 4-0. The member 40 is disposed horizontallyand extends inwardly and terminates flush with the inner surface of thesash panes. The hinge member 40 extends from. side rail to side rail ofthe sash and its opposite end fla e of which portions are securedthereto by means of angle brackets 41. These angle brackets have theirhorizontal flanges secured to the ends of the hinge member and havetheir vertical flanges riveted'to the web portions of the side rails ofthe sash frame. The bead portion 38 of the hinge member 37' and thegroove or socket portion 39 of the hinge member 40 are arranged in axialalinement with the horizontal sash pivots. With this arrangement, thespace between the top of the lower screen 35 of the sash is closedduring all positions of the sash,

and no movement is imparted to the screen when the sash is opened byreason of the alinement of the bead and, groove portions of therespective hinge members 37 and 40, the bead member 38 of the hingemember 37 merely rotating in the socket 39 of the hinge member 10 whenthe sash is swung open.

In the modification shown in Fig. 6, the space between the upper edge ofthe lower screen and the sash is closed by means of an inclined metalstrip 50. The lower end of this strip is clamped between the framemembers of the screen, and its upper margin is provided with a bead 51which presses against the sash panes. This strip is slotted to straddlethe intermediate vertical mullion' of the sash frame.
